Question
Comment on dilute solution and concentrated solution. Which of them gives the solubility of the solute? Explain.
✓
Answer
Dilute and concentrated solutions are relative terms. The solution obtained by dissolving one teaspoonful of salt in 100 mL of water is dilute compared to a solution obtained by dissolving two spoonfuls of salt in 100 mL of water. None of these gives the solubility of the salt. The idea of solubility can be obtained by dissolving the maximum amount of salt in a fixed quantity of a solvent at a given temperature. Solubility changes with temperature. In the case of a solid solution, solubility increases, but in the case of a gaseous solution, the solubility decreases.

The frictional force between two moving surfaces which are in contact with each other is called kinetic friction or sliding friction.
Example If a boy apply some pushing force on the box, the box will start sliding on the surface and the friction between the surfaces is called sliding friction.
The force required to keep a body in motion is less than the force required to start the motion, so we can say that sliding friction is less than the static friction.
(i) Explain why the sliding friction is always greater than rolling friction?
(ii) Mention two different examples for sliding friction.
